Using the CurrentCost meter and the graphing that has been setup, I noticed yesterday a 3KW spikethat lasted an hour, before dropping to 2.4KW for 40 minutes.
I had a feeling that my Storage Heaters were to blame, but wanted to double check. I am currently with Scottish and Southern Energy (SSE), and am on their SuperDeal tariff. A quick check on their website (which does not render in firefox on linux 😦 ) did not provide any tariff information. So after a lengthy phone call and the guy on the phone needing to refer to a book(!) I got my answer that between 2 and 4 in the afternoon I get a boost of electricity! Since then I have turned off the boost, and lowered the overall temperature on the heaters and today I am down 750W(ish) on yesterday which is a good start. Hopefully when this weather sorts itself out I can lower them further and save my precious pennies (and help “Save the Planet”!).
